Why you post 4 different hands into one thread.
It is very though to read and analyze all these hands.
Please post next time one-two hands per thread.
4) Rather than c/r, I like more bet turn and shove river.
But c/r is also fine.
3) Against that player it is b/f on the turn.
2) B/c flop, you don´t want to play stacks when you could easily see turn card and shove on safe turn card. It is very hard to call oop your 3-bet with worse hands.
1) I´d also b/f turn, since don´t expect that he´d turn his one pair hand into bluff
